CABLE-RING COMPRESSOR.

Application filed May 5, 1917.

To all whom it may concern:

Be it known that I, CHARLES HINNnR- Sl-IITZ, a citizen of the United States, residing at Mount Penn borough, Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Cable-Ring Compressors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skllled in the art to which it appertains to make and use the same.

This invention relates to tools, and mor particularly to tools especially adapted for compressing o1 crrmpmg cable rings in posltion, and has for its primary object to provide a cable ring compressor that can readily apply cable rings to various size messenger cables.

Another object of the invention is the provision of crimping blocks rotatably carried by the tool having a different size groove in each side face thereof, so that the crimping blocks can be shifted to bring the grooves in such position as to conform to the size of the messenger cable on which the rings are to be placed.

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, forming a part thereof, in which:

Figure 1 is a side elevation of the 1mproved cable ring compressor.

Fig. 2 represents an edge elevation of the improved tool with the handle removed, and

Fig. 3 represents a detail perspective view of one of the crimping blocks.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 1 generally indicates the improved cable ring compressor including the companion shanks 2 and 3 pivotally connected at one end thereof by the pivot pin 4 and having the laterally projecting ears 5 and 6 formed thereon. The laterally projecting ears 5 and 6 are reduced in thickness and receive the jaw bars 7 and 8, which are pivotally secured thereto by means of the pivot pins 9. Each of the jaw bars 7 and 8 consists of two members 10 and 11, having their free ends bent outwardly in opposite directions, as at 12, and thence Specification of Letters Patent.

Patented Nov. 11, 1919.

Serial No. 166,775.

bent forwardly in parallel relation to form spaced arms 13, which receive the crimping blocks 11, which will be hereinafter more fully described.

A connecting bar 15 is positioned between the members 10 and 11 of the jaw bars 7 and 8, and is pivotally secured to the same by pivot pins 16 and the connecting bar 15 is positioned intermediate the crimping block-receiving arms 13 and the pivotal connection of the jaw bars with the shank, and it will be seen upon inward movement of the shanks 2 and 3 toward each other the ends of the jaw bars 7 and 8 will be forced toward each other.

Each crimping block 11 is substantially oblong in formation and has a different side groove 17 formed in each side wall thereof and has a centrally disposed longitudinally extending aperture 18, which removably receives the pivot pin 19, which is extended through registering apertures formed in the spaced arms 13and supports the crimping block in position between the arms. The pivot pin 19 has a head 20 upon one end thereof, and the opposite end receives a. removable fastening element 21, which prevents accidental removal of the pivot pin.

The ends of the shanks 2 and 3 opposite the pivotal connection thereof are rounded, as at 22 and 23, to receive the cylindrical handles 2% and 25, which facilitate the operation of the improved tool.

In operation of the improved cable ring compressor the crimping blocks 14 are positioned so as to bring one of the grooves 17 in one of the blocks which conforms to the size of the messenger cable to which the rings are to be applied in alinement with the corresponding groove in the other crimping block, and then the same are applied to the ring and upon movement of the handles toward each other the crimping blocks 14 will be forced toward each other, thus compressing or crimping the ring in position on the messenger cable.

In practice, I have found that the form of my invention, illustrated in the accomchanges in details of construction, proportion and arrangement of parts may be resorted to, when required, Without sacrificing any of the advantages of my invention as set forth.

What I claim as new, is:

A cable ring compressor comprising a fulcrum bar, an arm having a U-shaped forward end pivoted, to each end of said bar, handles pivoted to each other and t0 the rear ends of said armsyshafts removably carried by the U-shaped ends of said arms, and a crimping block mounted on each shaft and having a different sized groove in each face, said block being spaced forwardly from said fulcrum bar for a distance less than their width to permit said block to 15 have a limited rotary movement on said shafts.

In testimony whereof I affix my signature in presence of two Witnesses.

CHARLES W. H-INNERSHITZ.
